Contextual Effects on Individual Voting Behavior: The Case of Taiwan

This study investigates the voting behavior of the Taiwanese electorate in two different levels of election by taking into account two aggregate-level effects, namely the political and economic contextual effects. Using both individual-level and aggregate-level data to study the 2008 legislative election and the 2012 presidential election in Taiwan, this paper not only confirms that the valence politics explanation outperforms other individual-level voting models in the legislative election and in other elections in Taiwan, but also demonstrates how the two contextual effects influence individual voting behavior. Specifically, the political contextual effect had influence on the individual electoral choice in both the 2008 legislative election and the 2012 presidential election, whereas economic contexts only affect voters’ decision when choosing a president. The multilevel analysis reveals that different individual-level voting models could provide partial explanation for voting behavior; however, the findings also show that we may overlook how contextual effects may affect the electoral choice.     

Histopathology mapping of biochemical changes in myocardial infarction by Fourier transform infrared spectral imaging

Fourier transform infrared (FTIR) imaging and microspectroscopy have been extensively applied in the identification and investigation of both healthy and diseased tissues. FTIR imaging can be used to determine the biodistribution of several molecules of interest (carbohydrates, lipids, proteins) for tissue analysis, without the need for prior staining of these tissues. Molecular structure data, such as protein secondary structure and collagen triple helix exhibits, can also be obtained from the same analysis. Thus, several histopathological lesions, for example myocardial infarction, can be identified from FTIR-analyzed tissue images, the latter which can allow for more accurate discrimination between healthy tissues and pathological lesions. Accordingly, we propose FTIR imaging as a new tool integrating both molecular and histopathological assessment to investigate the degree of pathological changes in tissues. In this study, myocardial infarction is presented as an illustrative example of the wide potential of FTIR imaging for biomedical applications.
